The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 19 - 13 y$$
Divide both parts of the equation by 2
We get the answer: x = 19/2 - 13*y/2
2*x+13*y = 19
Looking for similar summands in the left part:
2*x + 13*y = 19
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 19 - 13 y$$
Divide both parts of the equation by 2
x = 19 - 13*y / (2)
We get the answer: x = 19/2 - 13*y/2

$$x_{1} = - \frac{13 \operatorname{re}{\left(y\right)}}{2} - \frac{13 i \operatorname{im}{\left(y\right)}}{2} + \frac{19}{2}$$
x1 = -13*re(y)/2 - 13*i*im(y)/2 + 19/2
